Abstract

Sistema di abbattimento a caldo delle polveri nei fumi di combustione di inceneritori e centrali termiche comprendente un ciclone assiale attraversato dall'intero flusso di fumi caldi, un anello separatore del flusso di fumi in uscita dal ciclone assiale in un flusso primario a bassa concentrazione di polveri ed alta portata ed un flusso secondario ad alta concentrazione di polveri e bassa portata (10% circa della portata totale) ed un secondo stadio di filtrazione del flusso secondario, flusso primario e secondario caldi essendo immessi in uno scambiatore di recupero calore.Hot abatement system of dust in the combustion fumes of incinerators and thermal power plants comprising an axial cyclone crossed by the entire flow of hot fumes, a ring separating the flow of fumes leaving the axial cyclone in a primary flow with low concentration of dust and high flow rate and a secondary flow with high concentration of powders and low flow rate (about 10% of the total flow rate) and a second filtration stage of the secondary flow, hot primary and secondary flow being placed in a heat recovery exchanger.
